§    ABSTRACT: Three basic assumption should be satisfied in order to apply the MANOVA technique. In this study a pratical suggestion to be used in the case of departure from homogeneity of covariance is presented. Differences between the nominal and observed levels for the criteria Wilks' lambda L , Lawley trace T, and Roy's largest root R as function of the sum of the Euclidean distance between each dispersion matrix and the dispersion mean matrix are given.

§    KEYWORDS: One-way MANOVA model, heterocedasticity.
